Anti-Theft System



Entering Security Code

Most vehicles are equipped with Heidelberg V or VI radios that are equipped with a theft protection program. When the battery has been is disconnected or if the radio has been removed, the radio will lock-up electronically and cannot be operated until the security code is entered. On the Heidelberg V, if the proper code is not entered in six attempts, the radio will lock-up permanently and cannot be repaired. On the Heidelberg VI, two incorrect attempts will lock the radio for about 1 hour.

The Heidelberg V may have a code assigned at the factory or a personal code created by the owner. The Hiedelberg VI has a code assigned at the factory and entered by the dealer during pre-delivery inspection. New radios come with the code printed on a sticker but not entered into memory. All codes are 4 digits. To code the radio:

Be sure to make note of the radio code, which is supplied on a tag with the owner's information or recorded in the owner's manual. As an anti-theft feature, the code must be entered into the radio once power has been removed or any time the battery is disconnected.


NOTE
The radio will not operate until the code is entered, and if entered incorrectly more than 3 times, the radio cannot be reprogrammed for 24 hours.

If the radio goes into the SAFE mode, (3 missed coding attempts), the radio must be left ON for 24 hours before coding will be allowed.

  1. Turn the radio ON.
  2.  
  3. Press and hold the SCAN and SEEK buttons simultaneously until the radio displays the number 1000 and release the 2 buttons.
  4.  
  5. The radio preset keys are used to enter the radio code as follows:
  6.  


    Preset button No. 1 for the first digit
     
    Preset button No. 2 for the second digit
     
    Preset button No. 3 for the third digit
     
    Preset button No. 4 for the fourth digit
     

  7. If the first digit of the radio code is a '0' (zero), press button No. 1 until no digit is displayed in the first field.
  8.  

Example; if the radio code is 1423 program as follows:



Press preset button No. 1 as needed to display the number '1'
 
Press preset button No. 2, 4 times
 
Press preset button No. 3, twice
 
Press preset button No. 4, 3 times
 

  1. Press and hold the SCAN and SEEK buttons simultaneously until the radio displays SAFE and then a radio channel appears and release the buttons. The previous radio channel presets will be lost and must be reprogrammed.
  2.  

If the radio code has been lost, take the radio to your local dealer along with the VIN number of the vehicle, and the radio can be obtained through the manufacturer's dealer support network.

Heidelberg V
  1. Turn the radio ON . The radio should display the word SAF. DO NOT attempt to eject a cassette with the radio in this mode.
  2.  
  3. Push the AM/FM and SCAN buttons at the same time and hold them until the display changes, then release them immediately. The number 1000 will appear for about 3 seconds, then the display will go blank. Release the buttons then.
  4.  


NOTE
If the buttons are held too long, the radio will interpret this as an attempt to enter an incorrect code.

  1. Use the first four station selector buttons to enter the code. The first digit of the code is always 1. Each time the other buttons are pushed, the number in that position will change.
  2.  
  3. When the code appears correctly in the display, push the AM/FM and SCAN buttons at the same time. When the radio plays and displays a frequency, release the buttons.
  4.  
  5. If the code was entered incorrectly three times, momentarily disconnect the battery and try again. If the code is entered incorrectly three more times, the radio cannot be coded and cannot be repaired.
  6.  

Heidelberg VI
  1. Turn the radio ON . The radio should display the word SAF. DO NOT attempt to eject a cassette with the radio in this mode.
  2.  
  3. Push the AM/FM and SCAN buttons at the same time and hold them until the display changes, then release them immediately. The number 1000 will appear and remain in the display.
  4.  


NOTE
If the buttons are held too long, the radio will interpret this as an attempt to enter an incorrect code.

  1. Use the first four station selector buttons to enter the code. Each time a button is pushed, the number in that position will change.
  2.  
  3. When the code appears correctly in the display, push the AM/FM and SCAN buttons at the same time. When SAF appears in the display, release the buttons. The radio should play and display a frequency.
  4.  
  5. If the code was entered incorrectly two times, leave the radio ON for one hour and try again. This can be repeated as often as required.
  6.
